Agent skills are a standardized way to extend agent capabilities with specialized knowledge and workflows. It consists of a folder containing a SKILL.md file. This contains metadata and instructions for the agent to do its task.
Other stuff can be bundled with the skill as well, as follows.
agents-new-skill/
├── SKILL.md # Required: metadata + instructions
├── scripts/ # Optional: executable code
├── references/ # Optional: documentation
